A Balanced Arthroscopic Debridement of the Inner Layer of the Knee Retinaculum Increases the Tibiofemoral Joint Space Width

Figure 1

Concentric arthroscopic debridement of the inner reticulum. (a) A to D show a progressive sequence of the lateral debridement of the inner medial retinaculum. E to H show a progressive sequence of the medial debridement of the inner medial retinaculum. The asterisks show the lateral portal location, and the arrow shows the inner retinaculum. (b) The image shows the distal debridement, and the arrow shows the inner retinaculum. (c) The image shows the intact layer II of the retinaculum, and the arrow shows the inner layer of the retinaculum. (d) The image shows fibrin in the meniscus, and adherences are visualized at the inner layer of the retinaculum. (e) The image shows the debrided inner medial layer of the retinaculum, and the arrow shows the intact inner layer. (f) The image shows the inner medial layer of the retinaculum under debridement, and the arrow shows the intact inner layer. (g) The asterisks show the medial layer II of the retinaculum, and the arrow shows the inner layer. (h) The debridement is completed using a basket punch.
